Frequently Asked Questions (FAQs)

Frequently Asked Questions About Vacuum Tube Factories in China

What are the main vacuum tube factories in China

You have several key players in China when it comes to vacuum tube manufacturing. The primary factories include Shuguang, Psvane, and the relatively new LINLAI™. Shuguang, although it had a period of uncertainty, is now back in operation. Psvane, which originated from Shuguang, continues to be active in the Hi-Fi tube market. LINLAI™, founded by a team of engineers who previously worked at Psvane and Shuguang, is also making a significant impact.

What happened to the Shuguang factory

Shuguang had a bit of a rough patch. The factory was shut down in 2019 due to the sale of its urban land to a real estate developer, and there was uncertainty about its future. However, it has now resumed operations with the same equipment and some of the original team members, making it a separate entity from Psvane.

What types of tubes does LINLAI™ produce

LINLAI™ offers a variety of tubes, including triode tubes like the 300B, 2A3, 211, 845, 805, and 101D. They also produce rectifier tubes such as the 274B and preamp tubes like the 6SN7. More recently, they have started producing popular power tubes like the KT88/6550.

How does LINLAI™ ensure tube quality

LINLAI™ takes quality control very seriously. They use self-developed industrial-scale testing equipment for all tubes coming off the production line and also employ the advanced Amplitrex-AT1000 tube testing system to ensure accuracy and consistency. This rigorous testing process enhances the reliability of their tubes.

What sets LINLAI™ apart from other Chinese tube manufacturers

LINLAI™ aims to stand out by adhering to Western business standards and focusing on producing world-class tubes. Unlike some other Chinese manufacturers that may prioritize quantity over quality for the domestic market, LINLAI™ carefully selects and screens its tubes to ensure high reliability and performance, making them a compelling choice for international customers.
